BilingualTube - YouTube Bilingual Subtitles

Watch YouTube videos with bilingual subtitles. Display original and translated subtitles simultaneously to improve language learning and video comprehension.

Key Features:
• Bilingual subtitle display - Shows original text and translation together
• Official translation support - Uses YouTube's native translations when available
• API translation fallback - Supports Microsoft Translator (no API key required) and OpenAI
• Smart language detection - Automatically detects source language and handles language variants
• Clean interface - Subtitles overlay directly on the video player

How it works:
1. Install the extension
2. Open any YouTube video with subtitles
3. Configure your target language in the extension options
4. Bilingual subtitles appear automatically

Translation Options:
• Microsoft Translator - Free, no configuration needed
• OpenAI - Requires API key, supports custom prompts and models

Perfect for:
• Language learners who want to see both original and translated text
• Viewers who prefer subtitles in their native language
• Anyone watching foreign language content

The extension prioritizes official YouTube translations for better accuracy, and falls back to API translation when official translations are unavailable.

Privacy: No data collection. All translation requests go directly to your chosen translation service.
